Graphing is somewhat independent of metrics. A single metric can only be a single value at one time. What you want to do is create a graph that shows you multiple metrics on the same graph, like the cpu_report and mem_report you see at the top of most pages. You can do this using RRD's graph language. If you're running Ganglia 3.1, look in ganglia-web's graph.d/ directory for samples of graph definitions, and make a new file following the same form but with a different graph definition. Then add your graph's name to the array in get_context.php so it will show up as an option in the pulldown menu in the cluster view. You can also write your own dashboard to view all your custom graphs, something I thought I could move away from in 3.1 but turns out to still be necessary. It's pretty easy to see what forms the URLs for the graphs take from looking at the source of a ganglia-web page, and make your own page showing what you want, or your own program showing the sets of graphs you want together. -- Cos ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Ganglia-general mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/ganglia-general
